There are 12 men in the dance recital.
8x=32
X=4
3(4)=12
There are 3 pairs of earrings that you bought in addition to the jeans. Forming an equation with the given values helps to find the required value.
<h3>How to write an equation for the given information?</h3>
It is given that,
A pair of jeans cost = $44
A pair of earrings cost = $12
you spent a total of $80 before taxes.
So, the equation for the given data is,
$80 = $44 + $12x
Where x is the number of pairs of earrings.
<h3>Calculation:</h3>
Simplifying the obtained equation:
$80 = $44 + $12x
⇒ 12x = 80 - 44
⇒ 12x = 36
⇒ x = 36/12
∴ x = 3
Thus, you can buy three pairs of earrings at the mall in addition to the jeans.

Answer:
C.) each treatment is thought of as a value of the explanatory variable
Step-by-step explanation:
The main purpose for using randomization in an experiment is to control the lurking variable and establish a cause and effect relationship.
If we do not control lurking, or confounding, variables, we cannot accurately establish a cause and effect relationship; this means we cannot ensure that each treatment is a value of the explanatory variable.
Answer:
b. 75
Step-by-step explanation:
a(n) = a1 + d(n-1)
a(n) = 8.5 + 3.5(n - 1)
a(20) = 8.5 + 3.5(20 - 1)
a(20) = 8.5 + 3.5(19)
a(20) = 8.5 + 66.5
a(20) = 75
